Search for HEX (RHP) and a topic comes up that explains how to use macrobodies in general using RCC as an example.

thanks so much, it was helping, now I'm trying to write the input file and I counter something with the fill card, I tried to write it as matrix but I got confused should it be better to write it as rows ?

I can't say for sure try searching for some examples to see what others have done.
